Answer:

(x, y) =(2,-3)

Step-by-step explanation:

4x+3y=-1

3x-9y=33 /:3

4x+3y=-1.....(1)

x-3y=11... (2)

(1)+(2): 5x=10

x-3y=11

x=10/5

x-3y=11

x=2

2-3y=11

x=2

-3y=11-2

x=2

-3y=9

x=2

y=9/(-3)

x=2

y=-3

(x,y)=(2,-3)

Answer:

<h2>(2 , -3)</h2>

Step-by-step explanation:

4x + 3y = –1

3x – 9y = 33

12x + 9y = –3 (1)

3x – 9y = 33  (2)

We add equation (1) and (2)

12x + 9y = –3

+

3x – 9y = 33

___________

15x + 0 = 30

then x = 30/15 = 2

if we substitute x by 2 in equation (2) we get :

3(2) – 9y = 33 ⇒ 6 - 9y = 33 ⇒ -9y = 33 - 6 = 27⇒ y = 27/-9 = -3

finally, x = 2 and y = -3.

Simplify the given exponential expression.
Andrews [41]
The rule for multiplying similar bases with exponents is:

(a^b)*(a^c)=a^(b+c)

In this case you have:

In the 2004 Olympics, Adam won a gold medal in the men's 500 m kayak race, with a time of 1 min and 37.9 sec. He also won the br
Sedbober [7]

Answer:

The correct answer is Adam rowed faster in the men's 500-meter kayak race.

Step-by-step explanation:

To find the speed he rowed in both races, you need to divide the distance of the race by the time it took him to finish. In the first race, he rowed 500 meters and did it in a time of 1 minute 37.9 seconds, so the speed in that race would be \frac{500}{97.9} or approximately 5.10725 meters per second. In the second race, Adam rowed a distance of 1000 meters and did it in a time of 3 minutes 28.2 seconds, which means his speed in that race would be \frac{1000}{208.2} or approximately 4.80307 meters per second. Since his speed in the first race was faster than his speed in the second race, Adam rowed faster in the first race would be the correct answer.
